Elizabeth's take on this term...
Inflammation is the body’s response to being triggered by an external substance.
Autoimmune and other chronic conditions are conditions of inflammation in the body. Most, if not all, symptoms are due to inflammation.
Inflammation is not a mystery as there is always a trigger.
